GEARING FOR WASHING-MACHINES AND THE LIKE.

To all whom it may concern:

Be it known that I, ALVA J. FISHER, a citizen of the United States,residing at Evanston, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Gearing for VVashlowingis a specification. My invention relates to gearing for washing machinesand the main object thereof is to provide a simple and eflicientreversing mechanism for automatically reversing the direction ofrotation of the cylinder or operating mechanism within the tub orreceptacle of the .washing machine. Another object of my inventionis'tfo provide a simple and efiicient means for manually changing thedirection of rotation of the wringer which is operated from the sameprime mover as the washing machine The various features of novelty andutility of my machine will be apparent from the description hereinaftergiven.

In the drawings, Figure 1 is aside elevation of my washing machine andwringer embodying the operating mechanism constituting my invention;Fig. 2 is an end elevation thereof; Fig. 3 a section on the line 33 ofFig. 1 but on a larger scale; Fig. 4 a section on the line 4-4 of Fig.3; Fig. 5 an elevation of the reversing mechanism, the cover of itscasing being removed; Fig 6 a section on the line 6-6 of Fig. 5; Fig. 7a section on the line 7-7 of Fig. 5; Figs. 8 and 9 sections on the line88 and 9-9 respectively of Fig. 7 Fig. 10 a view similar to Fig. 9 butshowing a differentposition of the parts; Fig. 11 a detail view of theshifting block; Fig. 12 a detail view of a part of the casing of thereversing mechanism; Fig. 13 a detail view of the weighted view ofpinion 6 and its bushing. V

Referring to the embodiment of my invention as herein shown, the machinecomprises a receptacle or tub 1 of suitable shape and dimensions andsupported in suitable manner as by means of the series of uprights orstandards 2 and the cross-piece 3. The machine further comprises thewringer ,A suitably supported on one end of the receptacle, a motor suchas the electric motor 4 Specification of Letters Patent.

supported on the cross-piece 3, and the driving connections hereinafterdescribed, be tween the motor and the reversing mechanism and thence tothe rotatable cylinder 5 in the receptacle 1 and to the reversingmechanism for the wringer and thence-extending to the wringer itself.The motor drives a shaft 4" which may be thearmature shaft extended andalso drives what I will term a drivin shaft 6 through the medium of theshaft% and the couplings S-8, Fig. 1. The driven shaft extends into andhas its bearing ina casing. 9'provided with a plate 10 whereby suchcasing may be fixed to the frame of the machine in suitshaft is secureda bevel pinion 15 which" meshes withthe large bevel ear 16 secured tothe inclined drilven shaf t journaled in the casing 9 and is surroundedor sheathed by the concentric stationary tube 18 fitting at its lowerend over the tubular extension 19 of the bearing 20 for the shaft 17 andat its upper end fitting into the counter-sunk bearing 21 of the casingof the hereinafter described, Figs. 3 and 7. The driven shaft 17 alsocarries near its lower end and above the bevel gear 16 another bevelgear 22 adapted to mesh with a similar bevel gear 23 secured to thelower end of the substantially vertical driven shaft 24 which operatesthe wringer. The pinion 23 has an extended hub 23" journaled in thebearing 25 in the casing and the shaft 24 is surrounded or sheathed bythe stationary tube 26 in substantially the samemanner as the othershaft 17. The connections between thedriven shaft 24 and the wringerwill be hereinafter described.

Referring to the automatic reversing mechanism between the driven shaft17 '7. This shaft is journaled in the lower bearing 21 and an upperbearing 30 at the top of the casing and is held in place in 17 which is.

suitable manner as by means of the collar 31 secured to its upper end.The casing incloses all of the operating parts of the reversingmechanism and for the purpose of assembling the parts and to enable' easinspection the casing is provided with. a" removable front plate 32.

Upon the driven shaft 17 are loosely mounted the upper and lower bevelpinions 33 and 34 and intermediate these pinions there is mounted uponthis shaft a longitudinally-movable shiftable clutch sleeve 35 which"inconnection with the clutch faces, hereinafter described, on the inneradjacent faces of the pinions 33 and 34 constitute clutches for thepurpose of transmitting the motion between the driven shaft 17 and oneor the other of these two pinions. This clutch sleeve is keyed to theshaft by means of the longitudinal key 36 with the result that suchsleeveis rotatedvby the shaft 17 but has a longitudinal movementthereon.-

As shown more clearly. in Fig. 5 the upper pinion 33 has a clutch face33 on its inner hub portion and the other pinion 34 has a similar clutchface 34. The ends of the clutch sleeve have similar or companion clutchfaces, the upper end of such sleeve having a clutch face35 and the lowerend a clutch face 35 The sleeve is provided toward its central portionwith two annular shoulders or collars 35 either separate from orintegral with'the sleeve. Between these two shoulders is arranged ashifting block 37 shown indetail in Fig. 11, the same having alongitudinal'bearing opening 37 slightly more than a semi-circle andadapted to fit upon the shaft '17, as seen in Fig. 6. The shifting block37 is adapted .to be moved or shifted in a direction longitudinal of theshaft 17 by means of the lever 38 which is pivoted intermediate itslength upon the pin or stud -39 supported in the casing 27, Fig. 6. The

inner portion of this lever engages with the side recess 37" of theblock as seen in Fig. 11, such recess being of the irregular shape shownin order to accommodate the relative movements of t e lever and block.The innet end of 'th leverfcarries' an inwardlyprojecting pin 40 havingthe 'functibn hereinafter explained. The lever extends through anopening 27 in the casing which opening is in the form of a slot topermit of the rocking movements of the lever.

Upon one sidejofthe lever is a slidingplate 41 which is adapted to beprojected into the smaller opening 27? at one side of the slot by meansof'the handle [lever 42 when-it is desired to lock the shifting sleeve35 in its intermediate or neutral position as shown in i Fig. 5. Thislever is pivoted at 43 upon one side of the lever 38 and is operativelycon-- nected with. the slidingplate 41 by means of its stud 44 engagingan opening 41 in such plate. This plate .has a slot 41. co-

- erative lower ends bent operating with a stud 45 on one side of thelever 38 and also has another slot 41; on which the handle is mounted,with the result that by the rocking of the handle. 42 the plate 41 maybe projected into the slot 27 b to lock the lever 38 in such neutralposition as seen in Fig. 5 or may be"rocked to the opposite position forwithdrawing such plate from its locking position. The inner end of thislocking plate is beveled so that if the lever 38 is in either one of itsoperating positions it be withdrawn therefrom by the act of rocking thehandle-42, one of the bevel sides of the plate engaging one edge of theslot 27 and thereby forcibly withdrawing the lever from its operative to.rocked to the position shown in Fig. 5.

Both "of the pinions 33 and 34 are in constant mesh with the drum-shapedbevel gear 46 whose hub 46 is journaled in. the bearing 47 providedinthe casing 27.'- This bearing extends through an end wall of thereceptacle 1 and is held thereto by means of the nut 48 screwing on theinner end of such extended bearing, a gasket 49 being inter posedbetween-thenut and-the wall of the receptacle. These means constitute afastening additional to the bolts 29 for securing the casing 27 to thereceptacle. 1. The inner end of the hub 46 is angulafifor op-'connection with hub 55 of the cylinder or agitator within .thereceptacle. The

outer portion of the hub 46 has a central bore in which is secured andkeyed by means of the key 49 a shaft orbolt 50 having a screw-threadedportion 50 and having se-' cured to its outer end a disk '51. This screwthreaded portion receives a nut 52 which is provided with a dependingportion in order that such nut may be weighted and thereby ordinarilyprevented from rotating but compelled to travel longitudinally with respect to the longitudinal axis of the bolt 50. By preference this' nutis split at its upper end and such split ends are held by a cross bolt53, whereby the proper fit between the nut and the screw threads may beobtained and any wear-taken up. Also by preferencethe sides of the nutare provided with cushioning means for apurpose hereinafter explained,such means comprising the two similar flat springs 54 secured. at theirupper ends by the bolt 53 and having their v outwardly, Figs. 5, 8, 9and .10.

When the parts are in'the' position shown in Figs. '5 and position sothat the motion of the shaft 17 will not be communicated further thanthis sleeve, that is to say the pinions 33 and 34- will not be rotatedand conse bu ehtly the cylinder 5 "will not be operated time thesleeveis'n'ot in clutching engagement with either one of said twopinions.

7 the sleeve 35 is in neutral 1 ecause at this However. assuming thatthe sleeve is now shifted downwardly by hand through the medium of thelever 38 so that its clutch face 35 will engage the clutch face 34 ofthe lower pinion 34, as shown in Fig. 10, the rotation of the shaftcated to the pinion 34 and therefrom to the gear 46 and finally to thecylinder 5. The rotation of the gear 46 means a similar rotation of thebolt or shaft 50 and consequently the nut 52 will move longitudinally ofsuch bolt in a direction depending upon the direction of the threadthereon and also of course depending upon the direction of rotation ofthe bolt itself. Assuming that in the present instance the nut is movedto-. ward the right when viewed as in Fig. 7 it will move until-itsright-hand side rib 52 comes into contact with the projection 55 on oneface of the gear wheel 46 adjacent its hub portion, Figs. 6 and 8whereupon such nut will partake of the rotary movement of its bolt andthe gear wheel 46. The nut in its rotation will strike the pin 40 andthereby inclose the lever 38 and consequently shift the sleeve 35 to itsupper position shown in Fig. 9 the clutch between it-and the lowerpinion 34 and engaging the clutch between it and the upper pinionConsequently the pinion 33 will become the driving pinion and as it islocated diametrically opposite the pinion 34 with respect to the gear46. it follows that this latter gear will be rotated in the oppositedirection. In this rotation of the gear 46 and the bolt 50 in thereverse direction the nut 52 will move longitudi nally to the left, Fig.7, and the rib 52 on its left-hand side wil eventually come into contactwith the projection 56 on the inner face of the disk 51 with the resultthat the nut will be caused to rotate with its bolt.

In this rotation the nut will come in contact 7 with the pin 40 and willrock the lever 38 1n the opposite direction thereby unclutching thesleeve from the upper pinion 33 and puting it into clutching engagementwith the lower pinion 34 and consequently reversing the direction ofrotation of the gear 46. .The springs 54 serve as cushioning springs forcushioning the contact between the nut and the stud or pin 40. Bypreference the lever is provided with a spring 57 tending to hold thesame to a neutral position but the same is not essential and may bedispensed. with.

By the means above described the rotation of the-agitating devicewithin'the receptacle is automatically reversed by simple and eflicientmechanism. The duration of the periods of operation in one direction andthe other can be very readily adjusted in different ways, as forinstance by increasing or decreasing the length of the "threaded portionof the bolt 50 or by increasing'the extent of projection of theprojections 55 17 will be communiv termine the three positions named.

and 56 or by changing the'pitch of the screw threads because of a fasteror slower movement of the nut.

Referring to the operating connections between the other driven shaft 24and the wringer, reference is had to Figs. 1 to 4. The upper end of theshaft 2.4 is made angular to receive an angular-shaped tube or sleeve 58which is preferably pinned thereto by the pin 59. The upper end of thissleeve receives the lower angular end of a short driven, shaft 60 whichhas its bearings in the hubs 61 and 62' of two similar bevel gears 61and 62 respectively which are loosely mounted on said shaft 60. Thesetwo hubs are journaled in the bearings 63 of a suitable casing 63 whichhouses said gearing. On the shaft 60 intermediate the two pinions ismounted a clutch sleeve 64 which has an upper clutch face 64 and a lowerclutch face 64", the former being adapted to engage with a correspondingclutch face 62 on the pinion 62 and the latter with a correspomlingclutch face 61 on the lower pinion 61. This clutch sleev e is operatedby the handle 65 which is connected to a rocking cylinder 66 on whoseinner end is: mounted a roller 67 arranged eccentric of the longitudinalaxis of the cylinder which axis intersects the central lon gitudinalaXis of the shaft 60. This roller engages in an opening 64 in one sideof the sleeve 64 with the result that the rocking of the handle 65 willcause the sleeve to be raised or lowered to one or the other of itsoperative positions. In Fig. 3 the handle and sleeve are shown in theirneutral position but when the handle is turned to the dotted lineposition shown in Fig. 3 the sleeve will be raised so that the rotationof the shafts 24 and 60 will be communicated to the pinion 62, it beingunderstood that the sleeve is keyed to the shaft 60 so as to be rotatedthereby and to also have a longitudinal movement thereon. Vhen thehandle 65 is rocked down to its right-hand position, Fig. 4, the sleevewill be brought into clutching engagement with the lower pinion 61. Thedifferent positions of the handle 65 are determined and maintainedseparate as against positive force by the spr ng-pressed ball 68adaptedto engage in any one of the several. holes 66 which de- The twopinions 61 and 62 arein constant mesh with a. third bevel pinion 69which is secured to the outer end of the horizontal shaft 70 bearing inthe bracket casing 71 secured to one side of the wringer. The shaft 70is connected with the shaft 72 of the wringer roller by means of asuitable coupling such as the coupling 73. It will be understood fromthe foregoing description that when the sleeve 64 is in clutchingengagement with one of the pinions 64 or 62 it will drive 50 is a drivenshaft with respect to the shaft 17 and the latter is a driving shaft incomparison therewith, although a driven shaft in comparison to the shaft(3. In order to clearly distinguish the shafts 17 and 50 I have in theclaims referred to the former as in such hub a driving shaft and to thelatter as a driven shaft.

In order to prevent water from the tub passing by the hub 46* I providethe latter with a pacl'ing ring 46* located in a groove and pressedfirmly in the bearing 47 and thereby arranged to stand still during therotations of the hub.

As shown in Fig. 14, the shaft 6 of pinion 2 is journaled in a bushing-12 which is positioned in a hole in the casing 9 and made removable inorder to provide for motors of different speeds and for pinions 12 ofdifferent size. Each size of pinion has its own bushing and toprovidefor another size 'of pinion, another bushing and pinion are substituted.This is an important desideratum due to the fact that as users move fromone location to another where electrical current of different phase isused, the proper changes in the machine can be readily and economicallymade.
